How can the game be improved? This is my wishlist.

It is advisable to:

1. Expand the research trees by adding an additional level. This additional level could cost ten exotics (quarnium) and at least 30000 crystals and metals. This ultimate level of development must contain truly unique research and technologies. You can also add a very tempting condition: the maximum level of development can be unlocked if you have colonized and controlled at least ten planets (asteroids don't count). This is justified, as all technologies can be researched in just two hours. Large maps become boring without additional research.

2. Expand the list of unique ship and planetary artifacts. They make the game more engaging.

3. Increase the maximum ship development level. Upon reaching level 5, an additional slot can be granted. Upon reaching level 10, ships can be given a fifth unique ability.

4. Add unique objects (planets, stars, ancient structures) and special missions associated with them.

5. Add new maps with a large number of planets (>50).

6. Add realism. Weapons(missiles) must be depleted and replenished. You can also play with the speed of the missiles.

You also need to do something about the scaling in the game. Some objects look disproportionate to each other.
